I've changed the motherboard and cpu in my pc and I'm not sure wether I have have to buy a new copy of windows when I reinstall it. I know that the computer is defined by its motherboard and when I change it, it's pretty much a new computer. So when I reinstall windows will I need to buy a new copy of windows 7 or can I use the disc and code I have for my original version of windows 7.
(I've checked and I have the oem version of windows).

Per the Windows 7 OEM license agreement, you are required to purchase a new license as your old license is tied to your old motherboard.

That said, and as gotovato already stated, if you attempt to use your current Windows license on the new build, it will likely fail online activation. You should then be prompted with a phone number to contact Microsoft. When you do, it's quite possible (though not guaranteed) that Microsoft will re-activate your current license to run on your new motherboard.

I did the same thing recently. It won't activate at first but, the screen that comes up will give you a number to call for Microsoft. Call it. Follow the steps and they'll reactivate it for you.

Agreed.
The EULA says no. Whether Microsoft will Activate is at best a maybe.

Also, the only time Windows 7 is transferrable according to the EULA at least is via a repair build which means a different motherboard using the same socket (thus compatible with the same CPU).

*If it works great. It may be against the EULA but if Microsoft agrees then it's not illegal. I would then advise you to upgrade to Windows 10 if you see no obvious reason not to.
 
In some countries, Microsoft OEM EULA is against the local law up to certain extend.
In these countries, you might have the possibility that you do not have to buy new Windows and still can use the old license. This is working only via telephone activation, meaning you must call the local Microsoft support.
This is something you have to find out yourself accordingly to where you live.
